16. option d is correct Explanation:- According to given electronic configuration of B and C, B needs 3 electrons and C needs 1 electron to complete octet. Therefore, one atom of B will combine with three atoms of C. The molecular formula of the compound formed will be BC3. Also B represents Phosphorus (P) and C represents chlorine (Cl). Thus, formula of compound formed is PCl3 or BC3
